To all w/i am it may concern Be it known that I, FRANK W. Canon- LING, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Dust-Guard; and I do hereby declare the'following to bee, full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same, reference being bad to the accompany ing drawings, and to'the characters of ref erence marked thereon, which form a part of this specification.

This invention relates particularly to dust-guards for journal boxes, but is not restricted to such use, as it may be used in any connection for which it may be adapted or appropriate.

he object of my invention is the vision of character, which to manufacture,

pro-

is simple and inexpensive light, durable and strong in its construction,and adapted to fit closely within the soc ket provided therefor in the ournal box to edectually prevent dust and dirt from entering such box through the ournal-receiving opening therein, and to prevent an escape of lubricating matter from within the journal-box.

A further object of my invention is the provision of a dust-guard of this character, which comprises a minimum of parts in its construction, and which has its holder or ody member provided with opp o -t yielding bearing portions which'are intended to coact with the side walls of a journal box receiving socket to frictionally retain the ody member in snug position therein and to form close joints between the contacting t EOIHOKIS of the membersand the socket we a, whereb to enhance the emciency and practicability of devices of this clam.

A further ob'ect of m provision of a ust-guar collar or fioati part of which is invention is the of this the not carmeet by the journal, but on the m w is held in suspension by the op a sictional pressure of the'sides o the holder member thereagamst so that such part d not have beari contact with the 'ournal except in following the vibratory or eating movements of the journal, thus reducing an improved dust-guard of thisv box and journal wear and friction between such parts to a minimum, and materially enhancing the efficiency of the dust-guard.

further object of my invention is the jected in a more emcient manner than the of collars heretofore used for such purpose. I

The invention is fully. described in the following specification, and while in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof s illustrated in the accompanying drawings, in which' Figure 1 is a side elevation of a journal therein equipped with my invention, with portions in section. Fig. 2 is a side elevation of a dust-'ard em ing the invention with a part broken away. hig. 3 is an enlarged cr tion on the line-0am in Fig. 2, and Fig. d is an elevation of the dust-ard.

The holder memberhh ah centrally so u Hip its amfi:

. outwardly o lo portion for the journal 4 to project through, said opening being larger than the opening of the collar 6 to pernut a limited vibratory or floating movement of the journal therein, the opening 1 being preferably substantially the size of the journal box opening 2 and in axial register therewith when the dustguard is mountedin proper position within the socket 3.

The collar 6 is smaller in size than the chamber 5 of the holder member to enable the collar to have limited gyratory movements therein transversely of its openin axis, and the outer edges of the collar an chamber are preferab y substantially rectangular in form or of some suitable shape adapted to prevent a complete rotation of the collar within the chamber. The collar (3 is of a thickness to adapt it to snugly fit between the side walls of the chamber 5 for frictional coaction therewith, whereby the collar is yieldingly held byvthe holder in any position in which it may vibratory action of the journal, thus preventing any bindin action of the collar on the journal and re ucing to a minimum the wear incident to the coacting surfaces of the collar and journal. It is preferable to make the collar 6 of pressed fiber, but it is to be understood that I do not restrict myself to the. use of any particular material in the ma of the collar or any of the other parts of the dust-guard.

The holder member, coin rises, in the present instance, two reverse y formed duplicate side members which are stamped, drawn or otherwise suitably formed from sheet metal or any other ma- 7 terial adapted for the pur ose. Each 0 these &'de parts has its centra portion drawn as at 9, to codpe correspondin portion of the other side to torm the co ar receiving chamber 5,, the posing ortions 9 being preferably paraland suitably s aced to permit the vibratory movements 0 the collar 6 therein transversely The normal width of the width to cause the opposing wa 9 of the chamber to yieldingly grip the collar. 6, whereby to compensate or wear between the coacting faces of the collar and chamber walls and to maintain the frictional coaction of such parts during long periods of use. The side members 8-8 abut around the outer marginal edge or the chamber 5 and are riveted, welded, or otherwise suitably secured together close to the outer edge of the chamber, as indicated at po nts 10 in Fig. 2. The members '8 extend outward from their points of fastening, or from adjacent to the marginal edge of the chamber 5, in slightl divergent yie dmgly-spaced relation, and ave their on r edge or run portions tapered or curved 5 laterally in more that such portions be moved by the rate with the abrupt form, as indicated at 11,-to provide a marginal edge ened rim portion for the holder. The side edges of the rim .portion 11 are disposed without the planes of the chamber sides 9 so that when the dust-guard is inserted into the journal box socket 3 the outer edges of the tapered mar inal portions 11 coact with the opposing si es of the socket 3 to yieldingly's ace the chambered portion of the holder rom the socket sides, as indicated in Fig. 1. The normal width of the marginal edge or rim portion of the holder is slightly greater than the width of the socket 3 so of the holder are sprung inwardly to a greater or less extent by the socket walls when inserted therein, thus providing a double dust-tight joint around the edge of the holder member. It is evident that this construction not only enables dustguards of one side to be snugly fitted into journal box sockets of slightly varying sizes, ut also serves to efiectual y revent the assage of dust between the e ge portions of the holder member and the coactmg side walls of the socket.

A further advanta e construction of guar in that the spacing of the sides 99 of the chamber 5 of the holder member from the sides of the socket 3 and the yieldingly carrying of such side the outer edges or rim portion portions b rmits the chamis incident to this It is evident that my improved dust-guard is simple and inexpensive in its construction, and com rises only three parts-the collar 6,'an the two side members 8-8 of the chamber-two of such parts bein du licates and of such a nature as to ena le t em to be re idl stamped, drawn, or otherwise suitab y from sheet metal or other suitable material for such pu and also that the yieldingly spacing o the outer marginal edge portions of the holder provides a s'rmp e means for snugly retaining a dust-guard within a journal x socket in a manner to prevent rattlin and to eflectually prevent the passage 0 dust and dirt around said guard and into the journal box. Iwishit understood that my invention is arrangement of rts except in so far as such limitations are specified in the claims.
